Abstract:
45 Duroc-Landrace-Yorkshire crossbred weaning piglets with average weight of about 10 kg were divided into three groups.Two Chinese herbal feed additives(Ⅰ and Ⅱ),antibacterials and growth-promoter were supplemented respectively to feed in 3 groups(Chinese herbal medicine Ⅰ,Chinese herbal medicine Ⅱ and control group).Growth performance among the three groups was compared. Compared with the control group,average daily gains in the group of Chinese herbal medicine Ⅰ were increased by 6.54%,5.01%,4.49% and 4.74% respectively in the four stages,while the feed conversions were decreased by(1.55%),8.25%,5.65% and-0.03% respectively.Average daily gains in the group of Chinese herbal medicine Ⅱ were increased by 1.44%, 2.24%,4.12% and 4.55% respectively,while the feed conversions decreased by-2.50%,6.01%,6.21% and 1.08%.And the two were able to prevent 10-40 kg weigh piglets from diarrhea effectively.The results indicated that Chinese herbal feed additives Ⅰ and Ⅱ can obviously improve the piglets' growth performance.The efficacy is superior to antibacterials and growth-promoter.Keywords:

In this study, the pigs of three test groups were fed with three Chinese herbal medical feed additives which were put into ration with suitable proportion for 60 days. Compared with the control group, the average daily gain of three test group apartly increased 60 g, 130 g, 110 g. In which the second test group was more significant than control group(P0.05).The feed reward increased 11.76%and 5.88% .Economic benefits increased apartly 33.4%, 20.57%, 24.45% compared with the control group.The results show that the Chinese herbal medical additives can obviously increase performance of pig, and can substitute or partly substitute for antibiotic additivs to warrant the lasting development in raising pig and safe pork production.
